Melatonin Benefits

  • Sleep regulation, circadian rhythm restoration, antioxidant protection, immune system support, potential neuroprotection, anti-aging effects

NMN Benefits

  • NAD+ support
  • mitochondrial function
  • DNA repair support
  • metabolic resilience

Melatonin Dosing

0.5-10mg orally, typically 30-60 minutes before desired sleep time. Lower doses (0.5-3mg) often more effective for sleep onset

NMN Dosing

250-1000 mg/day oral|single or divided doses|daily supplementation in studies

Melatonin Side Effects

  • Drowsiness, headache, dizziness, nausea, vivid dreams, potential hormone interactions, daytime fatigue with higher doses

NMN Side Effects

  • nausea
  • headache
  • GI discomfort
  • flushing

Research Overview

Melatonin

Melatonin has extensive clinical research supporting its efficacy for sleep disorders, jet lag, and shift work sleep disorder. Emerging research investigates its potential anti-aging, neuroprotective, and immune-modulating properties with promising preliminary results.

NMN

NMN has a substantial preclinical and growing human literature centered on raising NAD+ levels. Research is strongest for biomarker changes and metabolic endpoints, while long-term aging outcomes remain under investigation.
